The Hitchhiker’s Guide Adventure Game — 20th Anniversary Edition
The Hitchhiker’s Guide to the Galaxy — 20th Anniversary Edition is an illustrated, Flash version of the classic Hitchhiker’s Guide to the Galaxy text adventure game, hosted by the BBC.
This is a game known for the difficulty of puzzles and it’s unforgiving nature. It is very possible to die or get into an unwinnable situation. Case in point: the infamous Babel Fish puzzle, which is both frustratingly hard and requires a item from Earth (if you’ve read, or even heard of the book you probably know what that means).
In a similar vein, the classic text adventure game Zork has been ported to a PHP version. Use the ‘login’ command to make an account so that you can save.
